There the shelf zone ends and the slope towards the deep sea begins . 那里陆棚地带终止，呈倾斜状进入深海。
2.
A relict fauna and anomalously coarse grains are common in the upper few feet of some shelf sands . 残余化石和异常粗的颗粒，通常出现于某些陆棚砂上部的几英尺内。
3.
During the early silurian , the corals of the erlangping trough and the graptolites of the xichuan shelf belonged to the south china province 在早志留世，二郎坪海槽的珊瑚与浙川陆棚的笔石属华南生物省。
4.
In the jurassic and cretaceous , generally it was also the shelf sea ( shallow sea ) , but there were lacustrine and lagoonal environments in different parts of the basin 侏罗纪白垩纪在总的浅海陆棚环境下，盆地不同地区也形成了湖泊和?湖环境。
5.
In the late permian and triassic , the basin underwent once again a large - scale transgression , and the depositional environment was shelf sea with delta locally 晚二叠世三叠纪盆地又经历了一次大的海侵， ?浅海陆棚环境，局部?海陆过渡三角洲相。
6.
In addition , by means of seismic profiles , the platform margin and the platform inner sag margin can be finally identified , integrated with distribution of organic reefs 分析中上奥陶统烃源岩沉积环境，重要的是寻找碳酸盐岩台地边缘、台地内凹陷边缘，从而能够确定台缘斜坡、台地内凹陷、陆棚等烃源岩沉积环境。

The major lithofacies palaeogeographic characteristics of the qiongzhusi age and early canglangpu age ( early cambrian ) are a land in middle hubei , the carbonate tidal flat surrounding the land , shelf and a basin in the south 早寒武世早中期岩相古地理格局由鄂中古陆、围绕古陆的碳酸盐潮坪、陆棚及南边的陆棚边缘盆地组成。
8.
The carbonate source rocks of middle - upper ordovician in tarim basin are widely distributed in different sedimentary environments at the same period such as platform margin slope , platform inner sag , continental shelf , abyssal basin , etc 摘要塔里水盆地中上奥陶统碳酸盐岩烃源岩在同一时期不同的沉积环境（台缘斜坡、台地内凹陷、陆棚、深海盆地等）中均有发育。
9.
From the late middle ordovician to the end of ordovician , the cephalopods , gastropods and corals in the erlangping trough , and the conodonts , coral , brachiopods , cephalopods as well as trilobites in the xichuan shelf were from the north china province 在中奥陶世晚期至奥陶纪末，二郎坪海槽的腹足类、头足类和珊瑚与浙川陆棚的牙形石、珊瑚、腕足类、头足类和三叶虫均属华北生物省。
10.
Six lithofacies palaeogeographic maps of doushantuo , dengying , qiongzhusi , canglangpu , and longwangmiao ages of late sinian and early cambrian have been made in the light of dominant facies and in the way to make stratigraphic map 中扬子地区上震旦统发育了从碳酸盐潮坪、开阔台地、浅滩、台地边缘、斜坡到台地前缘盆地等沉积，下寒武统下部主要?细碎屑岩和碳酸盐岩组成的混合型浅海陆棚沉积，上部变成碳酸盐潮坪、开阔台地、台缘斜坡和台缘盆地沉积。
